If you're looking for a 💯 %, hands down, truly professional, reliable, and knowledgeable company to do your waterproofing project...look no further! Everyone from start to finish was extremely helpful and polite from the Office Assistants to the Project Manager, to the hard working Employees who did the actual work! All were very respectful of my home and property inside and out, and made sure to clean up after completion. Each day they showed me what work was done, and what happens next. The waterproofing was finished by the date they stated, and was done as quoted. I highly, and only, recommend ABW for your waterproofing project.

We had an excellent initial visit with Konstantin this morning. he conducted a very thorough inspection of the entire house and left us with several must do improvements to help us understand and begin to tackle our mold concerns here at the lake house. We have a follow-up appointment in two weeks to understand what further steps need to be taken.

Constantine & Sergey completed a foundation repair job for our home. Within one day of my phone call request Constantine arrived at my home. He performed an inspection while explaining in detail his professional recommendations, anticipated costs and timeline for the job. Along with that he was most congenial and receptive to working within my budget means. Sergey followed up from my initial meeting and was equally knowledgeable and provided all the assurances that a homeowners is looking for when dealing with a new contractor. Both left me with complete confidence that I was in good hands and not just another customer. The workman arrived on schedule and completed the job all the while taking the time to be kind and engage with my elderly 98 father who sat outside throughout the job to amuse himself. Their genuine willingness to ensure that all my needs were met were matched only by their "going the extra mile". They're beyond 5*'s! Mary Zazzaro West Hartford

Konstantin T. came to look at the mold in our bathroom. He gave an honest, thorough assessment and educated us on how to maintain and prevent a mold-free bathroom environment. He was very personable and funny. Thanks, Konstantin! We will be looking forward to using your services again in the future.
